See here:

So here we have a person who comes to the United States and commits crimes of selling dope and the government asks me to put him in prison for 10 months. And then we have an American citizen who buys land, pays for it with his own money, and he moves some sand from one end to the other and government wants me to give him 63 months in prison. Now, if that isn’t our system gone crazy, I don’t know what is. And I am not going to do it.
